Outlook 2013, 2010, & 2007: Block Email Addresses and Domains

Blocking specific email addresses and domains are essential to controlling the amount of junk mail you get in Microsoft Outlook 2013, 2010, or 2007. You can add email addresses and domains to the block list by using the following steps.

  1. Outlook 2013 and 2010 users select the “Home” menu, then select “Junk” > “Junk E-mail Options“. Outlook 2007 users select “Tools” > “Options“> “Preferences” > “E-mail” > “Junk E-mail“.

  2. Select the “Blocked Senders” tab.
  3. Choose “Add…“.
  4. In the “Enter an e-mail address or Internet domain name to be added to the list” box, enter the name or address that you want to add. You can add entire domains or just an email address as follows:
    • username@domain.com
    • @domain.com
    • domain.com
      Outlook 2010 blocked senders screen
  5. Select “OK” when you are done.


I have performed these steps but it doesn’t work for me. Why isn’t Outlook blocking the messages?

Open the “Junk E-mail Options” screen and check under the “Safe Senders” tab to ensure the email address isn’t listed there. If an email address you wish to block is listed in your Contacts, uncheck the “Also trust e-mail from my Contacts” box on this screen.

    Question for JVBELG re: @Roberto Sison: When you create a new rule to block email addresses with specific extensions, is it necessary to use quotation marks (e.g., ‘.xyz’), and can you use semi-colons to separate different extensions in a list — or, should you write it exactly as in your example (i.e., ‘.asia’ or ‘.xyz’)?

    @Roberto Sison:
    Create an Outlook rule:
    “Apply this rule after the message arrives
    with ‘.asia’ or ‘.xyz’ in the sender’s address
    move it to the Junk E-mail folder
    and stop processing more rules”

    I want to block a sender who uses the same username but a unique domain name for each email he sends. How may i do this?

    What a misnomer.

    Blocking a sender, does not actually block a sender at all. All this does is redirect mail from those senders, to the deleted folder.

    That isn’t blocking. That’s filtering.

    What’s the difference, you say?

    If I block you from coming into my house, you never get through the door. That’s blocking. You can’t get in, you can’t see me, you are BLOCKED.

    Filtering simply says that you can see me, can come in the door, and then I show you to the exit. At which point I still have to get you to leave.

    How about you write an article that explains how to ACTUALLY stop email from unwanted senders from even coming into the mailbox?

    when I block the sender will they be aware? In other words will the sender received a ‘bounced message?

    I am receiving junk mail from a sender with no email address, just a name. Outlook can’t block these without an email address to block.

    How can I find out the address and block these emails?


  7. says

    Useful, but I have 6 accounts in my Outlook 2013. All emails are delivered to the same folder, which is not now the default account. When I junk mail sent to a non-default address, it isn’t blocked. I have to change the default account to add it to the blocked senders list for that account. Even then it isn’t always blocked! I’ve checked safe senders etc.
    Anyway, is there a quick way of adding a sender to ALL the accounts in one go?

    I want to block certain email ids that should not receive my mail event accidentally i send. Means out going email filtering like unsubscribe

  9. Nancy says

    I accidentally added a safe sender to my junk mail list, and now I can’t get it undone. I can’t find the sender in the list of blocked senders. I have done everything else to add the sender to my safe sender list, but it still goes into the junk file. It’s an email I get every day. Can anyone help? I am using MS Office Outlook 2007.

    @Mitch Bartlett, I want to send messages from blocked senders directly to the deleted folder without ever landing in the junk folder. However, I don’t want all suspected junk mail to go directly to the deleted folder without my review. If I check the “Permanently delete suspected junk e-mail instead of moving it into the Junk E-mail folder” option, won’t both blocked sender and suspected-but-not-reviewed-junk-messages go directly to the delete folder?
